英文摘要 | PURPOSE:To eliminate the overflow of electrons, to execute a uniform carrier injection operation and to obtain a strain quantum well laser whose gain spectrum is sharp and whose threshold value is low by a method wherein the lattice constant of a semiconductor forming a well layer is made larger than the lattice constant of a substrate. CONSTITUTION:A strain quantum well semiconductor laser where a semiconductor forming a well layer is composed of InXGa1-XAsYP1-Y or InAsZP1-Z and its lattice constant is larger than the lattice constant of a substrate is formed. X, Y and Z are set as 0<=X,Y, and Z<= Its manufacturing method is as follows: an n-InP buffer layer 14 is grown in 0.1mum on an n-InP substrate 15 by an MOVPE method; then, an InGaAsP barrier 12 is grown in 3mum; and an In0.8 Ga0.2As0.6P0.4 well 13 is grown in 40Angstrom on it. The growth operation of the well and the barrier is repeated five times; and a five-layer multiple quantum well structure is manufactured. In addition, a p-InP clad layer 11 is grown in about 11mum on it. A strain quantum well wafer manufactured in this manner is buried in a DC-PBH structure. Lastly, a p-side electrode and an n-side electrode are vapor-deposited. |
